This adds the Samsung 1404-001221 NTC thermistor to the
NTC thermistor driver. As far as I can tell it is electrically
compatible with the Murata 47K NTC thermistor.
This thermistor is mounted in a variety of Samsung products.

The DT binding oneline is included, I see no point in splitting
that into a separate patch.
